Application filed November 19, 1926, Serial No. 149,404.

The object of this invention is to provide afire place construction inwhich the main chamber is divided by a vertical wall so that theequivalent of two grates and fire chambers are used, and arrangementsare made 7 for conducting smoke and products of combustion froma newlyplaced body of fuel to the'ash pit below fuel'inactive combustion, onthe other side of the apparatus, for the purpose ofconsumingthe smokeand gases as they pass upwardly through the grate and fire toward apoint of discharge.

A further object is to provide, in connection with a twin; fire placeconstruction, a centrally located flue, one end of which may be placedincommunication with an ash plt below either grate, and an upper oroppositely located pipe connection for communication with the hue andbeing capable of being shifted and placed in communication with eitherfire chamber, so that the smoke from a newly placed body of fuel may betransferred to the other fire and there consumed. The principle is ofgeneral application. I

With the foregoing and other objectsfin view, the invention consists inthe novel construction and arrangement of elementsjd'escribed,illustrated and c'laimed, it being understood that,modifications may be made withinthe scope of the claims withoutdeparting from the spirit of the invention.-

In the form shown in Figures lto -8 inelusive the front wall of a casingor housing isdesignated-lO, the side walls are shown. at

11 and 12, a-nd a rear wall 13incl'udes or has formed therewith anoutwardly extending portion 14 providing a duct or smoke flue 15. Theupper portion of the housing is closed by a cover 1'6 carrying thereon apipe connection 1'7 1 for the fl'ue l8. I e.

, Fire chambers such as 20 are defined be tween front wall lOandvertical wall 2l,and

these firechambers arejseparated by a central vertical wall 22. A gratesuch as that shown at 23 is mounted in each side of the housing and onopposite rsides of wall 22, and the lining for the fire box,oneachsi'de,

is sho'wn at 24. Accessto the firefchambers' is obtained through doors25, and doors 26 provide access to the-ash pit27, below thev grate. r

An opening 28 con municateswith the ash pit 27, on each side o'fthevertical partition wall 22, and a-damper 29 is hinged at 29, inlinewit'h wall 22 and is adaptedto close openings 30 and31,0ne'opening'beingclosed at" a time, under the conditions indicatedbelow. In the closing movement the damper 29 contacts with ribs orelements 30 and the pipe being adapted to swing with ref'erence to saidflue. Theplate 37 and-theU- accommodation of a,

A transverse wall 33 isprovided with- Y shaped-pipe 361 are rigidly,connected, and I move-together. from the full line position of Figure 5toeither dotted line-position, so

that the pipe 36 at its front 'p'ortion' 'mayibe caused to register.with 5 either, opening 34 or 35', for the purpose of" establishingcommu nication between either fire chamber 20; and

by a pin,-'handle, or operating element 40, and in order to operatethedamper 29.5% the same time, I provide a bracket-4lrfixed at 42 withreference to thepipe 36 and the pin and including an offset portion 43engaging a crank end 44; of rod 45. A lower crank element 46 on rodengages an arm 47 of operating member 4:8controlling damper 29.

In the use of the apparatus, it may beas sumed that the fire above grate23 at the left of Figure 8 has been supplied with new fuel,

and the products of Combustion, or smoke,

' pass in the direction shown by the arrows,

through pipe 36 and flue 15, to the ash pit 27, at the right, damper 29having been properly positioned by the'operation of handle 10. The smokewill then pass upwardly "through the grate and through thebody off-uel-on'that sideofthe apparatus, and of central-vertical partition 22,the smoke being consumedby the eoked fire on that side, and the-draftwill be upwardly through the point of discharge, indicated at 18. I Theopening 35 permits of direct communication the U-shaped pipe--36, orswitch pipe, is

shifted by handle 40, so that the pipe will establish communication withopening 35,

and in this operation, the damper 29 will" establish communicationbetween ash-p1t 27 at the left and the vertical flue 15. It will beobservedtherefore, that elements 29 and 36, representing'the lowerdamper, and the U-shaped pipe, are reversely controlled, that is pipe 36establishes communication with the-left-hand combustion chamber 20 andthe damper 29 establishes communication with the right-hand ash pit 27"When han dle 40 is shifted there is communication'b'etween theright-hand combustion chamber 20 and the left-hand ash pit 27. r

In Figures 9 to 13, showing a modification, a central vertical wallseparates combustion chambers or fire chambers 51, and either one ofthe-upper longitudinal ducts 52 may Vbe,placed in communication withlower duct or pipe 53 by means of U-shaped pipe or switch 54, adapted toswing with reference to pipe or duct 53, and being mounted on plate 55controlled by rod56,

and the plate being guided by segmental arm 57 having its ends securedat 58 to transverse verticalwall" 59. The *mounting of U- shaped pipe54, at its lower end is equivalent to a pivotal mounting, and the pipeswings from the position of Figure 13 to a position in which it mayestablish communication be tween the upper right-hand pipe or duct 52and the lower duct 53.

Suitable grates 59 arepositioned above separate ash pits 60, on oppositesides of draft doors 62 is open. These doors are connected'by chains 63with opposite sides of damper 61.

The products of combustion and heated '7 air froin' that fire chamber orcombustion chamber 51 containing a newly burning body of fuel maytherefore be conducted belowthe grate 59 on the opposite side of theapparatus,either flue 52 and the lower duct 53 being employed for thatpurpose by an obvious control of front damper 61 and rear U-shaped pipe5% New fuel being added above'the grate just mentioned, the draft willbe through the other pipe 52, through chamber 65 and exhaust ordischarge conbelow each-chamber and an ash pit below each fire box, asmoke flue, and means for placing the lower end-ofthe smoke flue incommunicationwith either ash pit, a pipe adapted to swing with referenceto the upper end of the flue, a swinging plate on which the plate ismounted, and means for shifting the plate and pipe to position forestablishing communication between the flue and either combustionchamber.
